Debian Hardware :: CPU Heating On Toshiba Laptop

CPU fan apparently is not working with Debian (or Kernel, I don't know who's responsible for ACPI devices management. ).After setting up lm-sensors to show core temperatures, and running a simple "while(true);" C program, I noticed the fan doesn't turn on until the temperature reaches 80 degrees Celsius, and when it does, it runs at what appears to be full speed (VERY noisy). Also, it stays turned on at that speed even after temperature gets below 35 degrees Celsius. The only way to turn it off is to put the computer to sleep and wake it up again, but if I do the same procedure, it happens again.

I think it is related to some compatibility problem with ACPI devices because when I turn on the computer, I can't get the Fn keys to work, but after I suspend and wake it up, I can control the brightness using the Fn key and use the Play, Pause, etc. buttons. I read this has something to do with ACPI issues, the same as the fan control issues, because "try to suspend and wake up the computer" is something people usually tell to others with this problem (I assume just to confirm the diagnostic).Everything works fine on the pre-installed Windows Vista that came with the computer. It's definitely a compatibility problem.

I've read a lot in forums, even here, but I couldn't get any solution for this. I installed toshset but asks me to enable a Kernel module which I have no idea of how to load. I have no idea of how to load a Kernel module in fact.Also, I didn't want to believe, but I read there's no solution for this (at least, not one which doesn't involve a lot of knowledge on the matter).I'd like to stay with Debian, so I'm doing my last try here before installing other Linux Distro. I hope this problem is about Debian and not all Linux distros.My laptop is a Toshiba Satellite L355, Intel Pentium Dual Core T3200. I bought it in the end of 2008, so it's kind of old.
